is designed for technical conditions control of vertical, deviated exploitation and injection well.

Description

Features and Advantages

• is operated through a one-core cable of up to 5000 m in length, with computerized logging stations equipped with fast-acting analog-digital converters which allow to record the full wave picture (of GEKTOR type);
• tool conveyance to the investigation interval through the drill pipe (inner diameter 5 mm);
• measures elastic wave dynamic and kinematic parameters as well as acoustic noise and temperature;
• has a GR channel for geological cross-section references;
• EMDS sensor provides wall thickness and collars depth determination, different defects discovery such as fractures, corrosion interval, mechanical galling, centralizers and casing shoes depth location.
